    The output from the sensor unit can be plugged into an Eno Scientific Well Sounder for data collection and readout. It is designed to use very little power to conserve battery life.
  • Page 5: Flow Sensor Operating Range

    FLOW SENSOR OPERATING RANGE Eno Scientific flow sensors use a rotating impeller to sense the water moving through a closed pipe. As the water moves, it drags the paddles with it, producing a digital pulse as each paddle passes the sensor. Note that the pipe must be full for the impeller to accurately reflect flow.

    Water flowing too slow or too fast will not be measured accurately. Eno Scientific flow sensors measure flow over a range from 0.25 fps to 15 fps. It is important that the flow size be selected based on the flow rate to be measured and not the pipe size.The most common mistake in selecting a flow sensor is to oversize the unit and not be able to measure low flow.
  • Page 7: Flow Sensor Installation: Electrical

    FLOW SENSOR INSTALLATION: ELECTRICAL The flow sensor comes in two configurations: 1 – with a plugged cable for simple attachment to other Eno Scientific devices such as the Well Sounder. Installation is simple. Plug the cable into the compatible connector on the Well Sounder.

    The offset increases the accuracy in the operating range of the flow meter but also will yield a net flow when the flow rate is below the minimum or zero. Used to calculate total water pumped, this technique is not appropriate. Eno Scientific Well Sounder 2010 / 2010 PRO Page 9...
